Understanding how domestic plants react to these harsh conditions is critical for vegetation management. We investigated the leaf and root metabolomes of the xeric shrub Ajania tenuifolia, as well as its responses to hot and dry conditions. Although the leaf water content of plants in dry and hot habitat decreased significantly compared to plants grown at the more humid site, the levels of reactive oxygen species (ROS), total carbon (C), nitrogen (N), δ13C, as well as the C and N fractions, were largely conserved. These findings suggest that A. tenuifolia has maintained its oxidative homeostasis and carbon-water balance in the face of adverse conditions. Plants grown in the drier and hotter habitat exhibited an increased tendency to accumulate sugar, particularly trisaccharides in their leaves. This was accompanied by a reduction in the investment directed towards phenolic compounds in their roots. Under hot and dry conditions, N metabolism was stimulated as indicated by the synchronous increases of δ15N in both leaves and roots. Leaves accumulated photorespiratory and osmoprotective amino acids, while roots exhibited elevated levels of antioxidants and N-containing compounds. The present study demonstrated that A. tenuifolia employs a whole-plant resilience strategy involving stomatal regulation, ROS scavenging, and osmotic protection to cope with stressful conditions. Our results also underscore the significance of N metabolism in stress resilience in hot and dry conditions, and offer valuable insights for vegetation management in arid and semi-arid areas under changing climate.","PeriodicalId":20164,"journal":{"name":"Physiologia plantarum","volume":"178 5","pages":"e71154"},"PeriodicalIF":4.0,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149220531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Gas signaling molecules are endogenous gaseous compounds that can freely diffuse across biological membranes. They mediate interplant communications and plant signaling transductions, with representative members including nitric oxide (NO), ethylene (Eth), hydrogen sulfide (H2S), and methane (CH4). Multiple studies have revealed that gas signaling molecules and histone acetylation can interact to dynamically regulate plant growth and stress responses. This review examines the current knowledge on the role of gas signaling molecules, as well as their synergistic effects with histone acetylation in plants. Specifically, NO can regulate flowering by S-nitrosylating HDACs and influence fruit ripening by inhibiting HDACs. In addition, both NO and Eth can affect seed germination, seedling growth, and pathogen resistance by regulating acetylation levels. Additionally, H2S can modulate root development in plants by regulating histone deacetylation. However, the interactive relationships among NO, Eth, and H2S, as well as the interplay of other gas signaling molecules and histone acetylation in plants warrant further in-depth research. The existing problems and future research directions are also discussed.","PeriodicalId":20164,"journal":{"name":"Physiologia plantarum","volume":"178 4","pages":"e70998"},"PeriodicalIF":4.0,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148382675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is crucial to understand how crops respond to early nitrogen deficiency. In the present study, we analyzed the responses to early nitrogen deficiency in komatsuna (Brassica rapa var. perviridis) plants, a popular leafy green vegetable in Japan. Komatsuna plants were grown in pot cultures under seven nitrogen levels (0, 30, 60, 90, 150, 210, and 270 mg N per pot), with nitrogen as ammonium nitrate. Shoots were harvested every 5 days from 14 to 39 days after sowing to measure dry weight, total nitrogen, and nitrate concentrations. The dry weight of komatsuna shoots increased significantly even after soil inorganic nitrogen was nearly exhausted. Under the 30 mg N treatment, nitrogen accumulation at 24 days accounted for 81% of the final accumulation at 39 days, whereas dry weight accounted for only 35% of the final value. This indicates about 65% of the final dry weight accumulated after nitrogen accumulation plateaued. To elucidate the molecular mechanisms enabling growth sustained by internal nitrogen, gene expression profiles in leaves were analyzed using RNA-seq in plants grown under marginal or ample nitrogen supply. The results indicated that transcriptional regulation of purine metabolism plays an important role in adaptation to early nitrogen deficiency. These findings contribute to the optimization of nitrogen fertilization by providing a foundation for developing markers to assess the need of top-dressing and for breeding crop varieties with high nitrogen-use efficiency.","PeriodicalId":20164,"journal":{"name":"Physiologia plantarum","volume":"178 4","pages":"e71002"},"PeriodicalIF":4.0,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148391537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As an important flowering repressor, FLOWERING LOCUS C (FLC) has been widely studied. FLC expression is mainly regulated by a variety of histone modifications, and the interplay between active and repressive markers determines the final expression levels of FLC. In this review, we provide a comprehensive overview of the roles of FLC in response to vernalization, the autonomous pathway, hormones, and diverse stresses. Furthermore, we summarize 153 regulatory factors of FLC across different flowering-related pathways, including 77 vernalization-related, 45 autonomous pathway-related, and 31 hormone- or stress-related regulators listed in appendices. We mainly focus on the positive regulation of FLC by the FRIGIDA (FRI) protein complex before vernalization, the establishment of mitotically stable H3K27me3-mediated repression during cold, which is maintained after vernalization and constitutes the 'memory of winter cold', the maintenance of this epigenetic memory in warm temperatures, and the resetting of FLC expression after fertilization. In addition, chromatin modifications, RNA-based post-transcriptional regulation, and post-translational modifications of FLC are reviewed in the autonomous pathway. Finally, we discuss how hormone pathways and stress signals converge on FLC to fine-tune flowering. The molecular mechanisms governing precise FLC expression provide a classic example of plant gene regulation and a useful framework for studying the function of other genes.","PeriodicalId":20164,"journal":{"name":"Physiologia plantarum","volume":"178 4","pages":"e70992"},"PeriodicalIF":4.0,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148391568","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 8503 M2 plants were screened for brown rice ionome using inductively coupled plasma mass spectrometry (ICP-MS). Candidate mutants were selected based on robust Z-scores (|Z-scores| > 2) of the elements for individual plants, resulting in the isolation of 38 mutants. To validate the screening process, two mutants were characterized in detail: high grain As (osabcc1-3) and low grain Zn and Cd (oshma2-4). Whole genome sequencing of the mutants and the correlation between phenotype and genotype in the F2 population indicated that OsABCC1 and OsHMA2 are likely the causal genes. The osabcc1-3 mutant carries a splice-site mutation at the exon-intron junction of OsABCC1, whereas oshma2-4 harbors a 3.3 kb insertion in OsHMA2. Notably, oshma2-4 exhibited similar growth and yield to BRRI dhan84 in a paddy field, suggesting its potential for breeding low-Cd rice. Together, these results demonstrate the effectiveness of ionomic screening in Bangladeshi rice for uncovering allelic variation controlling metal homeostasis and provide valuable genetic resources and physiological insights relevant to rice improvement.","PeriodicalId":20164,"journal":{"name":"Physiologia plantarum","volume":"178 4","pages":"e70980"},"PeriodicalIF":4.0,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13296837/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148318513","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we investigated the differential molecular mechanisms from stress perception to phenotypic response by integrating comparative transcriptomics, physiological profiling, and metabolic pathway analysis.

Despite its importance for both predictive modelling and biological control strategies based on oophagous parasitoids, the thermal biology of egg development remains poorly understood. This study aimed to address this gap by collecting pods bearing eggs and incubating them under 11 constant temperatures ranging from 12°C to 40°C. Egg development through four morphological substages was monitored daily. Data were organised as stage-frequency matrices and life-tables' parameters were estimated through an optimisation problem that reconstructed the distributions of stage-specific development times. Early substages (S1-S2) were generally longer at lower temperatures, whereas differences among substages became minimal within the optimal thermal range of 20°C-35°C. At 40°C, development ceased at stage S3, preventing egg hatching. The proposed method provided reliable estimates of development time distributions and showed consistent thermal responses across substages. These findings provide the first quantitative baseline for the egg development of B. rufimanus and offer valuable parameters for physiologically based models. Moreover, they supply essential information for synchronising parasitoid releases with susceptible egg stages, thereby supporting the development of sustainable integrated pest management strategies.","PeriodicalId":20164,"journal":{"name":"Physiologia plantarum","volume":"178 4","pages":"e70986"},"PeriodicalIF":4.0,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13373347/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148456234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
